ABSTRACT: It is always the main obstacle of the engine’s development that the thermal load. Taking the diesel engine block-coolant jacket as an examplethis paper establishes the fluid structure interaction model, and simulates and calculates the flow and the heat transfer of the block-coolantjacket. The results agree well with the measured data. And then this paper makes appropriate optimization to the structure of the coolant jacket according to the simulation results, puts forward two structure improvement projects, and also compares their simulating results, so proves the rationality of the structure improvement.

Keywords: Engine block, Coolant jacket, Heat transfer, Fluid structure interaction, Structure improvement.
